Milbank PB-032 – Frequently Asked Questions

1) What sizes does the Milbank PB underground termination cabinet come in?
Three box sizes are offered: 4x12x8.5, 6x12x26, and 6x16x36 inches, ordered as PB-011, PB-012, and PB-032 respectively. All three are the same 600V, 10,000A short circuit rated Type 3R cabinet, so the choice comes down to how much room your conductors and lugs need for the underground termination and how the box lands on the wall or pedestal. Pick the size from your conductor count and bend radius, not from the rating, since that does not change across the three.
2) Can the Milbank PB termination cabinet be mounted outdoors?
Yes. The PB termination cabinet is a Type 3R enclosure, which is the rating for outdoor use against falling rain, sleet, and ice formation. The shell is G90 galvanized steel with a powder coat finish in ANSI 61 Gray, so the corrosion protection is on the base metal as well as the topcoat. Type 3R is not a washdown or dust-tight rating, so keep it off any spot that gets hosed down or sits in blowing dust.
3) Will the Milbank PB cabinet accept aluminum service conductors, or do I have to pull copper?
Either one. The PB termination cabinet is rated for both copper and aluminum conductors, so an aluminum underground feeder is fine and you don't have to change conductor material to use it. That matters on the cost side of a long underground run, where aluminum is the usual choice.
4) Is a 10,000A short circuit rating enough for my service, or do I need a higher AIC enclosure?
The PB cabinet is rated 10,000 amperes short circuit at up to 600 volts AC. If the available fault current at that point in your system exceeds 10kA, this cabinet is not the right pick and you need a higher rated termination enclosure. Get the available fault current from the utility or your coordination study before you commit, because on larger commercial services fed from a big pad transformer, 10kA is commonly exceeded.
5) Is the Milbank PB a meter socket, or just a pull and termination box?
It is a termination cabinet for line-to-load distribution, not a metering enclosure you can meter a tenant through. It carries a single meter position designation, so treat it as the box where the underground service conductors land and transition, with metering handled by a separate socket or meter stack. If you are trying to meter multiple units, this is the wrong product family and you want a meter stack instead.
6) Is the Milbank PB underground termination cabinet UL Listed for a permitted commercial job?
Yes, the PB termination cabinet is UL Listed, along with the Type 3R enclosure rating. That is the pair an inspector looks for on an outdoor service termination, and it is what lets it be used on a permitted commercial or multi-family install rather than only in a utility-owned application.
7) Which Milbank PB box size should I use for a small underground feeder tap versus a full service termination?
For a shallow tap or a splice point where you just need conductors landed and covered, the 4x12x8.5 (PB-011) is the compact option. A full underground service termination with larger conductors and lugs needs depth and height for bending room, which is what the 6x12x26 (PB-012) and the 6x16x36 (PB-032) give you. All three carry the same 600V and 10,000A ratings, so sizing up buys you working space, not more capacity.
8) Can I use the Milbank PB termination cabinet on a 480Y/277V system?
Yes. The cabinet is rated for up to 600 volts alternating current, which covers 480Y/277V three phase as well as the 208Y/120V and 240V systems more common on residential and light commercial underground services.
9) Will the Milbank PB cabinet match the gray gear already on my building?
The finish is ANSI 61 Gray powder coat, which is the standard gray used across switchgear, panelboards, and meter equipment, so it lines up visually with most existing electrical gear on a commercial wall. The coating sits over G90 galvanized steel, so a scratch in the powder coat does not immediately put you into rust.
